The book, written by author Elin Meek and published by CAA Cymru, is aimed at adults who are learning Welsh at the Mynediad (Entry) level or above, and tells the story of the tenor who became famous for his role in the Go Compare television advertisements. Signed copies can be bought at the event.

The book is part of the Amdani series, which has been developed specifically for adults learning Welsh, and have been graded at four levels – Entry, Foundation, Intermediate and Advanced. The project is funded by the Welsh Books Council, and will be published jointly by four leading publishers, with the support of the National Centre for Learning Welsh.

On publishing Wynne Evans – o Gaerfyrddin i Go Compare, Delyth Ifan, CAA Cymru Director said: "We're delighted to present these new books for adults learning Welsh. As well as being suitable for learners, these books are suitable for people who may be fluent Welsh speakers but lack confidence in reading the language. I would also encourage anyone wanting to reacquaint themselves with the language to read them."

Phyl Brake, Aberystwyth University's Learn Welsh Coordinator said: "This booklet is the honest, entertaining and compelling account of the singer from south Wales. It is authored by someone who has many years experience in teaching Welsh as a tutor, examiner and as a course writer herself. The vocabulary and language patterns used are relevant and structured, and a short list of new vocabulary can be found at the bottom of each page. Wynne Evans' story is sufficiently gripping to sustain the reader's interest throughout, while, at the same time, constant repetition ensures that learners at all levels, familiarize themselves sub-consciously with relevant vocabulary and basic language patterns."

Efa Gruffudd Jones, Chief Executive of the National Centre for Learning Welsh added: "This new series of books will support current Welsh courses and will be an essential resource for Welsh learners in classes. We're delighted they are being offered on graded levels – this will certainly help increase confidence amongst learners. We hope that this project will attract learners to reading Welsh books in general."

Other events to promote Cyfres Amdani will be held at the National Eisteddfod in Cardiff in August, and the remaining titles in the series will be published in October.
